Forest Variations 2020-02-24

New forest variations.

Spoiler :

Top row:
New snowy forest 1, new snowy forest 2, default snowy forest (for comparison)
Second row:
Savanna*, default leafy forest (for comparison), bamboo forest
Bottom row:
Tropical forest (leafy and jungle combined), hybrid forest (leafy and evergreen combined)

* The savanna is based on the savanna graphics by Pie. I removed all transparent trees and redundant shadows.

XML is included.

This is how it looks if Blue Marble is installed:
